    magnaflow muffler swap

    I looked at the catback which seems to be a 5x8 oval muffler 18 inches long and it is 3 inches pipe size from the resonator.

    Anybody swap put stock muffler for Maganflow 3in/3in 22inch length 30 overall length part number 12579 or 14579 which is a 5x11 muffler or 12279 which is a 5x8 oval muffler? There is also a 30 inch length round 6 inch muffler they make part number 12641 or polished at 14641.

    I am thinking of cutting off resonator and stock muffler then using one of the above mufflers that are longer to keep the rasp down and am looking for a little more volume and bass tone but not quite sure which way to go so I was looking for opinions or to see if anyone has done one of the exact mufflers I posted above.

    Thanks!

    Do you have a mid pipe/y pipe?
    My setup is MBRP SS off-road y pipe. Stock resonator delete. with 3in/3out Magnaflow SS round muffler#14719 with a 3.5 MBRP turn down dump under the bed. To me it sound perfect. Nice deep tone. Non raspy. Idel and cruising speeds is not crazy loud but you know you have some type of aftermarket muffler. I love it. Also you still here your turbo spools. I think if you have the stock y pipe your turbo spools with be alittle softer.

    I've got the 18" Magnaflow with Solo catted downpipes. Sounds great, deep tone, no drone. I did the Magnaflow first, before the downpipes and the tone was slightly higher but still pleasant.

    Well If anyone else can contribute, I am looking at keeping everything stock except changing out the resonator and muffler to add a little sound and flow a little better. What I was trying to accomplish was my own version of a catback since they are mostly 3inch from y pipe back and different muffler. I was not looking to go crazy loud on sound since its a v6 but add some deep bass tone and hear the turbo whistle a smidge more without being raspy or crackly. So i was thinking of a long ass magnaflow 3 inch in/out muffler.

    I installed a Flowmaster dBX muffler with a 3" straight pipe in place of the resonator to the stock Y-pipe. I kept the stock tail pipe. The dBX is a straight through using Flowmaster's laminar flow technology - ideal for turbos. It definitely uncorked the exhaust at less than half the price of the cheapest cat-back.

    Nice rumble at normal throttle, no drone and with my Unleashed tune, it definitely helped over the stock setup. And even with the stock tune, it greatly reduces the turbo lag (I'm stock as I plan to take it in for Service shortly).

    Here's a link to Flowmaster's website. Oh, it's also stainless steel too.

    And if you want to consider a custom exhaust larger than 3", consider the Pro Series version. I may do that in the future after I install my catted Full Race DP.
